In your Setup project, select Project + Add, Merge Module. Navigate to c:\program files\common files\merge modules and select "Microsoft_VC90_CRT_x86.msm" to get the C/C++ runtime DLLs deployed to the target machine. There might be additional ones you need, like ATL, MFC, OpenMP, you didn't specify the exact dependencies in your question.
Beware that you'll have these merge modules available only if you have VS2008 installed on your machine. If you don't then it is strongly recommended that you rebuild the DLLs or libraries you use on VS2010, you cannot effectively support your product otherwise. If necessary, deploy the installer provided by a 3rd party if that's the way you ended up with a dependency on these DLLs.
